Abstract

Il trovato si inserisce nel campo delle macchine e dei procedimenti per il trattamento di fibre chimiche.Più precisamente si riferisce ad un procedimento di crettatura e ad una crettatrice meccanica in cui la spinta sul fascio di fibre in transito è esercitata da mezzi di spinta (1) atti a mantenere un contatto continuo e forzato con il fascio di fibre su una superficie estesa dello stesso.Detti mezzi di spinta (1) comprendono nastri chiusi (4) scorrevoli su rulli (2, 3) alla stessa velocità di ingresso del fascio di fibre.E' inoltre prevista un'iniezione di vapore nella direzione del moto del fascio di fibre e verso opposto.The invention is part of the field of machines and processes for the treatment of chemical fibers, more precisely it refers to a crimping process and a mechanical crimping machine in which the thrust on the fiber bundle in transit is exerted by thrust means (1 ) capable of maintaining continuous and forced contact with the bundle of fibers on an extended surface thereof. Said thrust means (1) comprise closed belts (4) sliding on rollers (2, 3) at the same input speed as the bundle of There is also an injection of steam in the direction of the motion of the fiber bundle and in the opposite direction.
